jolli1 [7]

Answer:

D is the correct answer.

Step-by-step explanation:

Distribute (−6x^4 + x^2 − 1)(2x^3 - 4x + 3)

-12x^7 + 24x^5 - 18x^4 + 2x^5 - 4x^3 + 3x^2 - 2x^3 + 4x - 3

Combine Like Terms

-12x^7 + 26x^5 - 18x^4  - 6x^3 + 3x^2 + 4x - 3

Paul [167]
The whiteboards she bought cost $35, and she spent a total of $51.20, subtract to find out the total amount she spent on posters:

\sf 51.20-35=16.2

So she spent a total of $16.20 on posters, now divide by the amount one poster costs to find out how many posters she bought.

\sf 16.2\div 5.4=\boxed{\sf 3}

So she bought 3 posters.

The vertex of the parabola below is at the point (3,2) and the point (4,6) is on the parabola. What is the equation of the parab
nata0808 [166]

Answer:

\large\boxed{y=4(x-3)^2+2\ \bold{vertex\ form}}\\\boxed{y=4x^2-24x+38\ \bold{standard\ form}}

Step-by-step explanation:

The vertex form of a parabola:

y=a(x-h)^2+k

(h, k) - vertex

We have the vertex at (3, 2) → h = 3 and k = 2.

Substitute:

y=a(x-3)^2+2

The point (4, 6) is on athe parabola. Put the coordinates of this point to the equation:

6=a(4-3)^2+2       <em>subtract 2 from both sides</em>

6-2=a(1)^2+2-2

4=a\to a=4

Finally:

y=4(x-3)^2+2          <em>vertex form</em>

<em>use (a - b)² = a² - 2ab + b²</em>

y=4(x^2-6x+9)+2          <em>use the distributive property</em>

y=4x^2-24x+36+2

y=4x^2-24x+38             <em>standard form</em>
